On the Present State of the Problem of Gravitation
The first domain of physical phenomena where a successful theoretical elucidation was achieved was that of the general attraction of masses. The laws of weight and of the motions of celestial bodies were reduced by Newton to a simple law of motion for a mass point and to a law of interaction for two gravitating mass points. These laws have proved to hold so exactly that, from an empirical point of view, there is no decisive reason to doubt their strict validity. If, despite this, one can scarcely find a physicist today who believes in the exact validity of these laws, this is due to the transformative influence of the development of our knowledge of electromagnetic processes over the last few decades.
